小程序语音（A）发给别人(B)，也能播放，是需要先把语音上传到自己的服务器上才可以。

定义公用语音包组件
const recorderManager = wx.getRecorderManager();
const innerAudioContext = wx.createInnerAudioContext();
//开始录音的时候
start: function() {
const options = {
duration: 10000, //指定录音的时长，单位 ms
sampleRate: 16000, //采样率
numberOfChannels: 1, //录音通道数
encodeBitRate: 96000, //编码码率
format: \'mp3\', //音频格式，有效值 aac/mp3
frameSize: 50, //指定帧大小，单位 KB
}
//开始录音
recorderManager.start(options);
recorderManager.onStart(() => {
console.log(\'开始录音\')
});
//错误回调
recorderManager.onError((res) => {
console.log(res);
})

//停止录音

var end = e.timeStamp;
var seconds = (end % (1000 * 60)) / 1000;

//这里也能按照时间显示留言宽度，暂时没做
var src = res.tempFilePath; //语音临时文件
//先把语音上传到自己的服务器上才可以，然后把返回的语音放入数组存储，最后在一起存到数据库中的字段里
